Exe file not working on different PC

[Shalini Mehra]

My program works fine if I run the program.py file in a python environment.
The command used was:-
pyinstaller --noconfirm --onedir -D --add-data "poppler location;./poppler" "program.py"

Then i use pyinstaller to create an executable using onedir option,
When this exe file is run in a different PC(Not having python installed) I get an error. What can I do to set it right? The error is:-

Traceback (most recent call last):
